Synthesis and Magnetism of Dinuclear Cu (Ⅱ) Complexes Bridged Through Iodanilic Acid Anion
Abstract:
The preparation and characterization of a series of dinuclear copper(Ⅱ) complexes, Cu2L2IA(ClO4)2, are presented. The ligand L is 1,10-phenanthroline(phen), 5-nitro-1,10-phenanthroline(NO2-phen) and 2,2'-bipyridine, and IA denotes the dianion of iodanilic acid. The complexes are characterized by elemental analysis, IR, electronic spectra, ESR and variable-temperature magnetic susceptibility measurements. The coordination geometry of copper(Ⅱ) ion is probably a distorted square pyramid. Room-temperature ESR spectra of all the complexes studied show the ΔMs=±2 half-field transitions. The variable-temperature magnetic susceptibility of Cu2(phen)2IA(ClO4)2 had been measured (4.2~300 K) and the exchange parameter, J, was found to be -29.18 cm-1 using the Heisenberg model. This indicates that an antiferromagnetic interaction exists between the metal ions.
